Omega watch: Researchers develop new blood test for measuring levels of critical omega-3 fatty acids

A new blood test has been developed to measure the levels of critical omega-3 fatty acids in the bloodstream, providing a convenient way to assess cardiovascular and cognitive health. The Omega-3 Index (O3I) is derived from two key fatty acids, EPA and DHA, which can be obtained only from certain dietary sources.

Evidence from the remains of 1918 flu pandemic victims contradicts long-held belief that healthy young adults were particularly vulnerable

Researchers found that individuals with previous environmental, social, and nutritional stressors were more likely to die from the flu. This contradicts the widespread belief that healthy young adults were disproportionately affected. The study analyzed skeletal remains of 369 victims and identified lesions as indicators of frailty.
